FIG. 1 is a block diagram illustrating a stacked type semiconductor memory device in accordance with example embodiments.

Referring to FIG. 1, a stacked type semiconductor memory device 10 of example embodiments may include a base die 100 and a stacked structure 200 stacked on the base die 100. The stacked structure 200 may include a stacked chip package including a plurality of core dies 310, 320, 330 and 340 sequentially stacked,

In example embodiments, the semiconductor memory device 10 may include a high bandwidth memory (HBM) structure or a hybrid memory cube (NMC) structure in which the base die 100 and the stacked structure 200 may be electrically connected with each other through a connection via 210 such as a TSV and a connection bump 220 to increase numbers of input/output units, thereby widening a bandwidth. The connection bump 220 may include a micro bump,

A plurality of memory cells configured to store data and circuits configured to operate the memory cells may be arranged in each of the core dies 310, 320, 330 and 340. Each of the core dies 310, 320, 330 and 340 may include a memory region corresponding to at least one channel. The core dies 310, 320, 330 and 340 may receive a signal, a power, etc., from the base die 100 through the connection via 210 corresponding to the channel,

The base die 100 may perform various functions of the semiconductor memory device 10. For example, the base die 100 may enable a power management function performed by partially activating the memory cells, thus enabling a timing control function between the core dies 310, 320, 330 and 340 and the base die 100.

The base die 100 may receive a command, an address, data, etc., from a controller, The base die 100 may then transmit the command, the address, the data, etc., to the core dies 310, 320, 330 and 340.

The base die 100 may include a physic& region PHY, a connection via region TSV and a test electrode region DAB.

The physical region PHY may be an input/output region of an address, a command, data, a control signal, etc. The physical region PHY may include input/output circuits, input/output terminals, a power supply terminal and an impedance control circuit. Numbers of the input/output circuits may be determined in accordance with a data-processing speed required in the semiconductor memory device 10. The input/output terminals may be configured to receive signals for input/output operations. The power supply terminal may be configured to receive a power.

The test electrode region DAB may include an interface circuit by which a memory controller may directly access the semiconductor memory device 10. The interface circuit may include a direct access ball and an output driver.

The connection via region TSV may perform a signal-processing operation, for example, a buffering operation with respect to a signal received from the physical region PHY or a test signal received from the test electrode region DAB. The connection via region TSV may then transmit a buffered signal to the core dies 310, 320, 330 and 340 through the connection via TSV.

In example embodiments, the stacked structure 200 may include a master core die 310 and slave core dies 320, 330 and 340, The master core die 310 may be arranged at a lowermost layer of the stacked structure 200. The master core die 310 may be directly stacked on the base die 100. The slave core dies 320, 330 and 340 may transmit and receive signals with the base the 100 through the master core the 310. Identifications may be provided to the core dies 310, 320, 330 and 340 of the stacked structure 200. The master core the 310 may have a structure substantially the same as that of the slave core dies 320, 330 and 340. Since the structure of the master core die is the substantially the same as that of the slave core dies, each 310, 320, 330, 340 is labeled CORE DIE in FIG. 1. The slave core dies 320, 330 and 340 may be classified as the master core die 310 in accordance with stack positions.

The master core the 310 may process the command, the address and the data transmitted from the base die 100. For example, the master core die 310 may buffer the command, the address and the data. The master core die 310 may decode the command. Further, the master core die 310 may transmit the command, the address and the data to the slave core dies 320, 330 and 340 through the connection via TSV. The master core die 310 may transmit signal-processing results to the base the 100. Further, the master core die 310 may receive signal-processing results of the slave core dies 320, 330 and 340 through the connection via 210. The master core die 310 may then buffer the signal-processing results of the slave core dies 320, 330 and 340 followed by transmitting the buffered results to the base die 100.

Therefore, the master core die 310 may include a circuit for buffering or decoding the signal transmitted from the base die 100 or the slave core dies 320, 330 and 340, The circuit may be activated to perform the buffering operation or the decoding operation. In contrast, because the slave core dies 320, 330 and 340 may be operated by receiving the signal and the command from the master core die 310 to output the signal-processing results to the master core die 310, a circuit for buffering or decoding the signal may not be activated.

According to example embodiments, a current consumption of a non-used circuit in the slave core dies 320, 330 and 340 may be blocked to reduce a current consumption and a power of the semiconductor memory device 10.

Thus, the power control circuit 303 may apply the first power voltage VDD1 to the first power terminal 311 and the ground voltage VSS to the second power terminal 321.

When the core die 300 in FIG. 2 may be used as the slave core dies 320, 330 and 340, the first circuit 301 may not be used to implement the signal buffering or the decoding. In this case, the power control circuit 303 may apply the ground voltage VSS to the first power terminal 311 and the second power terminal 321 to control a current consumption of about 0 for the first circuit 301.

When the die ID DID<> may represent the master core die 310 and the stack enable signal EN3DS may be activated, the current regulation circuit 3033 may apply the first power voltage VDD1 to the first power terminal 311.

When the die ID DID<> may represent the slave core dies 320, 330 and 340 and the stack enable signal EN3DS may be activated, the current regulation circuit 3033 may apply the ground voltage VSS to the first power terminal 311.

The stack state identifier 3037 may output the die attribute signal SLAVE in response to the determination signal DET and the stack enable signal EN3DS.

In example embodiments, when an ID of 00, 01, 10 and 11 may be assigned to the master core die 310 and the slave core dies 320, 330 and 340 and the stack enable signal EN3DS may be activated, the die attribute signal SLAVE may be outputted to a high level only when the corresponding die may not correspond to the master core die 310.
